Hmm, I'm at work, about to link to a game involving a guy being at work and killing himself. Weird.
Anyway! The game is called Karoshi, which translates as "death from overwork". Your objective in each level is to kill your little blue suited guy by figuring out how to get him impaled, crushed, shot or electrocuted.
I should point out that this is more fun (and a lot less nasty) then it sounds. The puzzles are pretty clever and get really fiendish by the end.
So have fun!
